BONDED WOOD COMPOSITE FOR DOUBLE FLOOR AND DOUBLE FLOOR STRUCTURE USING THE COMPOSITE
To provide a double-floor wood composite that is strong enough to be constructed using only a jointed wood composite with an actual joint without floor base material.SOLUTION: A double floor wood composite 1 is a rectangular member composed of a wood core 1a and wood fiber boards 1b and 1c laminated on both upper and lower surfaces of the core 1a. A male fruit 2 is provided on two adjacent sides of the wood core 1a, and a female fruit 6 is formed on the remaining two sides. The length L2 to the tip 6f of the lower piece 6b of the female fruit 6 is formed larger than the length L1 to the tip 6e of the upper piece 6a. Thereby, the bonding length of the lower piece 6b side becomes larger than that of the upper piece 6a side, and the bonding force of this portion is increased compared to the actual coupling of the upper and lower pieces 103a and 103b having the same length. Therefor, even if a tensile stress due to the bending is applied to the actual joint portion H when the wood composite material A, which is bonded downwards with a load F applied to the double floor, bends, the fracture at the portion H does not occur.SELECTED DRAWING: Figure 2
【課題】本発明は、床下地材なしの実継ぎによる接合木質複合材だけの施工で強度的に十分な二重床用の木質複合材の提供をその課題とする。【解決手段】二重床用の木質複合材１は、木質芯材１ａと、該芯材１ａの上下両面に積層された木質繊維板１ｂ・１ｃとで構成された矩形の部材である。木質芯材１ａの隣接する二辺に雄実２が設けられ、残る二辺に雌実６が形成される。雌実６の下片６ｂの先端６ｆ迄の長さＬ２は、上片６ａの先端６ｅ迄の長さＬ１より大きく形成されている。これにより、下片６ｂ側の方が上片６ａ側より接着長さが大きくなり、この部分の接合力が上・下片１０３ａ・１０３ｂが同じ長さの本実結合に比べて増大する。そのため二重床に上から荷重Ｆが掛かって下方向に接合された木質複合材Ａが撓んだ時、この実継ぎ部分Ｈに前記撓みによる引っ張り応力が加わったとしても、この部分Ｈでの破断が発生するようなことがない。【選択図】図２
